ln carrying out the present invention, it-i is my purpose to provide a motor '.dliiven lire engine wherein motion. may be transmitted to the driving axle of the vehicle from the driving motor independently of the pump and, conversely, the pump driven from the drivingmotor independently of .the driving axle of' the vehicle.

Furthermore, I aim toprovide a vehicle of the typ-e above set forth' wherein the speed of the pump pistons may be stepped up as the vworlrvon the pump increases, incident to the lengthening of the pipe lines and the like. A

lt is also my purpose to provide a motor driven :lire engine wherein the transmis- 'i sion gear system o'f the driving axle may be employed in ii'nparting motion to the pump from the driving motor of the vehicle independently of the driving axle of such vehicle and' wherein the driving, axle ,may receive motion from the driving. motor through such transmission gear system independently of the pump, so that the speed of the pump may be stepped up commensurate with the water consumption and without the necessityl of employing an additional ear system.

lt is a "so my purpose to provide amotor iiie engine wherein4 in uneoiiplin the driving axle of the vehicle from t'e driving motor, the engine will' be coupled up4 to the driving mechanism'of the pump and vice versa, uncoupling of the driving mechanism of the pump from the driving motor,

the driving axle of the vehicle will he placed in driving engagement with the" motor;

The invention hasy for a still further object the provision of a motor. driven fire engine which will embrace' the desired features of' simplicity, eliiciency and durability and which may be operated ,and maintained' at a relatively small cost.

the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and vfalling within the scope of the claims.

been illustrated one preferred and practical embodiment of my invention, and in these ldrawings; Figure 1 is a top plan View of a motor re engine constructed in accordiance with the present invention, the body of the vehicle being removed. Fig. 2 is a `longitudinal sectional view through the lbody of the vehicle, parts being shown in 'View on the line 3 3 of Fig. 2. Fig. 4 is lemental frame and pump guides. Fig; 5 1s an enlarged plan view ,of the main] driving shaft of the vehicle, showing the various clutches for placing .the driving axle and pump in and out of engagement with the motor, parts being shown in section. Fig. 6 is a transverse sectional view of the vpump crank shaft, a portion of the pump :driving mechanism being shown in eleva tion.

' ln carrying my invention into practice, I. prefer touse a reciprocating pump, and Asuch pump is driven from the main driving shaft of the vehicle preferably by means and worm wheel, while the main driving fsh'aft of the vehicle is preferably in the form of two sections coaxial with each other and adapted to -be coupled and uncoupled "by means of a4 clutch tov place the driving Iaxle of the vehicle in .and out of driving mechanism of the pump is similarly con trolled and l have found it advantageous to i so interconnect the clutches as to render one o lerative while the other is inoperative so at when the pum is performing its duty, the driving axle o the vehicle will be disengaged from Vthe motor and vice versa when the driving axle is operatively cou.-

jof driving engagement therewith.

As my improved motor tire engine is ,driven by an explosive engine, employing hydrocarbon gas, the speed of the pump has 'to be stepped up gradually to prevent chok- IingI of the engine and consistent with the load of water consumption and to accom plish this stepping up of the speed of the In the accompanying drawings there has I of a driving mechanism embodying a worin.

`elevation Fig. 3' is a transverse sectional '70 an enlarged perspective view of the sup- A fengagement with the motor. The driving IOO pled upto the motor, thepump will be out pump I employ the transmission gear system of the vehicle and the vehicle driving axle, according to the conditions prevailing.

Referring now to the accompanying drawings in detail, 1 designates the main frame or chassis of the vehicle carrying at its forward end steering wheels 2, while to the rear end the-reof are connected the driving or tract-ion wheels 3 journaled upon the extremities of an axle l and equipped with sprocket wheels 5. Mounted upon the fprward end of the lchassis in any suitable manner is a driving motor 6 preferably in the form of an explosive engine and including the usual crank shaft 7 carrying at one extremity the fly wheel 8. Arranged longitudinallv of the main frame or chassis of the vehicle is a main driving shaft 9 coaxial with the engine crank shaft and terminating at one extremity adjacent the fly wheel 8, such extremity of the main driving shaft carrying a clutch l0 of any suitable or preferred construction and adapted to be slid into and out of driving engagement with the Vcrank shaft, the clutch frictionally contacting with the fly wheel to couple the engine and driving shafts, as usual. Any suitable form of clutch maybe utilized for this purpose and thereforea detail description of the same is deemed unnecessary for the purposes of this invention. The opposite extremity of the driving shaft 9 is operatively connected with a driving axle or shaft 11 through the medium of the usual differential gear 12. This driving axle 11 is arranged transversely of the main frame or chassis of the vehicle and at right angles to the main driving shaft thereof and is equipped at each end with a sprocket wheel 13 over which and the respective sprocket wheel 5 i of the traction wheels are trained endless chains 14. Thus, it will be .seen that when the driving motor of the vehicle is in operation, motion will be transmitted to the main driving shaft 9 by wav of the clutch 10 and fiy wheel 8, thence to t-he driving axle or shaft 11 and traction wheels 3 with the effect to propel the vehicle.

The variable speed transmission gear Vsystem of the vehicle is indicated at 115 and in accordance/with the present arrangement of the various parts of the vehicle is located im- Vmediately adjacent the clutch 10, the main driving shaft 9 of the vehicle being connectedto this transmission gear system in the i `ordinary well known manner, and as this transmission gear system may be of any preferred or selected form, a detail description of the same is not here given. l Mounted upon the main frame 1 of the vehicle, a suitable distance beyondthe driving motor, is a supplemental frame 16 arranged transversely of the mainframe or chassis andV composed. in the present instance, of divergingjlsidejbraces 17, 17 and crossv bars 18, 18 interconnecting the side braces and held spaced from the main fra-Ine by such braces. This supplemental frame is adaptred to support the seat of thev operator in control of the vehicle, and depending from the cross bars 18, 18 of the frame, are spaced parallel guides or track ways 19, 19 of any 'suitable or preferred construction. A

As before stated, the pump is preferably of the reciprocating type and in the present instance is composed of a pair of cylinders 20, 20 in each of which is mounted for reciprocation a piston 21 provided with a piston rod 22 projecting outwardly of the upper end of the respective cylinder. cylinders are preferably beneath the main driving shaft 9 of the vehicle andheld in place by means of suspension brackets 23 bolted or otherwise secured' to the main frame of the vehicle. The free extremity of each piston rod 22 is connected to the lower interconnecting bar 24 of a cross head 25 including spaced parallel side bars 26, 26 interconnected at their lower extremities and fastened tothe bar 24, and connected at their upper extremities, a wrist pin 28 being connected to the upper extremities of the bars 26,-26. These cross heads 25 are mounted for Sliding movement within the guides or track ways 19, 19 and aredesigned to be These reciprocated to impart movement to the pump pistons so that the pump may perform its duty when operatively connected to the motor.

The crank shaft of the pump is indicated at 29 and as shown is arranged transversely of the main frame of the vehicle and located mit a similar movement to the cross heads within the guides so as to impart a reciprolcatory movement to the pump pistons.

The driving mechanism of the pump is preferably in the form of a worm and worm gear and comprises the worm 31 loosely encircling the drive shaft 9 and held against longitudinal movement thereon, and worm wheel 32 keyed to the crank shaft of the pump between the/sliding cross heads and in mesh with the worm on the vehiclev driving shaft. This worm 31 `is adapted to be yplaced in and out of driving engagement with the main driving shaft 9" of the vehicle and for this purpose is equipped at one extremity with a reduced collar 33 provided with a toothed surface 34 adapted to be engaged by a sliding collar 35 having a toot-hed surface adjacent the toothed surface 34 of the collar 33 an provided with a circum- Aao 'till tornava ferential groove 36 receiving a yoke 37 carried upon one extremity of an operating lever 33 pivoted as at 39 to an appropriate part of the vehicle frame. The collars 33 and 35 form a clutch and when lthe collar 35 is slid into engagement with the collar 33, the teeth of the collars interlock to place the worm 31 in driving engagement with the driving shaft, the collar 35 being splined to the driving shaft forl sliding movement to accomplish this result.

ln order to disconnect the driving shaft or axle 11 of the vehicle from the main driving shaft 9 when the pump is clutched up to the mainA driving shaft, l form such main driving shaft of tWo sections and 41 coaxial with each other and equipped with a clutch, one member 42 of which clutch is keyed to the section 40 of the shaft, while the opposite member -43 of the. clutch is splined to the section 41 of the main driving shaft for sliding movement and formed with a circumferential groove 44 in which is disposed a yoke 45 connected to an operating lever 46 pivoted as at 47, the clutch -members 42 and 43, having their proximate surfaces toothed so that when the clutch members are engaged with each other, the teeth will interlock with the effect to drive the `section 40 from the section 41.r

The operating levers 38 and 46 of the respective clutches, are controlled from a common lever located within convenient reach of the operator upon the seat of the vehicle and designed, when moved in one direction, to disconnect the clutch of the pump driving mechanism from the shaft and connect thc clutch of the vehicle driving mechanism to the shaft and when moved in the opposite direction to disconnect the clutch of the vehicle driving mechanism and connect the. clutch of the pump driving mechanism. This common clutch throwing lever is indicated at 48 and is pivoted as at 49 to an appropriate part of the vehicle and has connected thereto at one side of its pivotal connection with the vehicle, a link 50 connected to the operating lever 46, and upon the opposite side of the pivotal connection with the vehicle frame, a link 51 connected to the operating lever 33.

The worm wheel 32 is preferably com` posed of a plurality of sections, as shown in Fig. which are bolted or otherwise secured in wheel formation, so that the worm wheel may be removed from the crank shaft of the pump whendesired.

The air dome of the pump isindicated at 52 and as shown is preferably disposed adjacent the foot board of the vehicle and in proximity to the operators seat.

From the foregoing description taken in connection with the accompanying drawings, the construction and mode of operation, i'

of my invention will be readily apparent.`

Assuming the clutch throwing lever 48 to be in the position shown in Fig. 5, the driving motor of the vehicle will be connected up to the driving axle 11 through the medium of the clutch 10, main driving shaft 7 and differential 12, the clutch composed of the members 42 and 43 coupling the sections 4() and 41 of the main driving shaft to propel the vehicle. Should it be desired to couple the pump t0 the driving motor, the lever 4S is thrown with the effect to uncouple the sections 40 and 41 from each other and place lthe clutch member 35 in engagement with the clutch member 33 whereby the worm 31 will be keyed to the section 41 of the main driving shaft with the effect to rotate the crank shaft 29 of the pump and slide the cross heads 26 within the respective guides and so reciprocate the pistons of the pump.

'it will be noted that the traction wheels of the vehicle may be disconnected from the driving Amotor and the pump placed in driving engagement therewith without stopping the motor or disengaging the clutch 10 from the fly wheel, 8 and furthermore, it will be seen that the above operation will be accomplished by a single lever and without the use of a plurality of clutch throwing devices. Further, it will be seen that the speed of the pump may be stepped up in accordance with the conditions prevailing through the medium of thetransmission gear system of the vehicle thereby eliminating the employment of an additional variable speed gear system.

While l have herein shown and described one particular embodiment of my invention by way of illustration, it is to be understood that l do not limit or contine myself to the precise details of construction herein de` scribed and delineated, as modification andv variation may be made within the scope` of the claims and without departing from the spirit of the invention.
